What are the different types of tides?
There are two types of tides: spring tides and neap tides. Spring tides occur when the moon is in its first or last quarter phase, and the gravitational pull of the moon is at its strongest. This causes the tides to be higher than usual. Neap tides occur when the higher than usual. This happens because the Earth and moon are aligned in such a way that the pull of the moon and sun on the Earth's oceans is at its greatest.
